Queues snake outside the courts wherever Joao Fonseca is playing - meaning only the forward planners and most patient are rewarded.
It will be the same when the 18-year-old Brazilian - who had never played a main-draw Grand Slam match until this year - meets Britain's Jack Draper in the French Open third round on Saturday.
The pair will play on Court Simonne Mathieu, the third show-court where unreserved seating in the top tier will likely lead to a scramble.
Most outside of the tennis bubble have never heard of Fonseca, but the world number 65 is creating a real stir inside it.
